所以我制作了一个IRC机器人，这是代码：
import socket
import sys
server = "irc.esper.net"
channel = "#stencyl"
botnick = "MrGutsy"
irc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print "connecting to:"+server
irc.connect((server, 6667))
irc.send("USER "+ botnick +" "+ botnick +" "+ botnick +" :This is a fun bot!\n")
irc.send("NICK "+ botnick +"\n")
irc.send("PRIVMSG nickserv :iNOOPE\r\n")
irc.send("JOIN "+ channel +"\n")
while 1:
text=irc.recv(2040)
print text
if text.find('PING') != -1:
irc.send('PONG ' + text.split() [1] + '\r\n')
if text.find(':!hi') !=-1:
t = text.split(':!hi')
to = t[1].strip()
irc.send('PRIVMSG '+channel+' :Hello '+str(to)+'! \r\n')
if text.find(':!water') !=-1:
t = text.split(':!hi')
to = t[1].strip()
irc.send('PRIVMSG '+channel+' :*brings water '+str(to)+'! \r\n')
这是我执行程序时得到的结果：

它似乎连接到IRC服务器，但没有加入频道.... 怎么了？？
答案 0 :(得分：1)
正如@spectras注意到的那样，你必须先等一下才能发送JOIN。
关键是来自服务器的回复：
:stormlight.esper.net 451 * :You have not registered
这意味着您在完成注册过程之前发送了一个命令（PRIVMSG和/或JOIN），我猜它会回复PING。
通常（和良好）的做法是在MOTD完成后发送初始消息，即。当您收到376命令时。
偏离主题的评论：您应该考虑using SASL而不是向NickServ发送PRIVMSG。它现在是在IRC上进行身份验证的标准。
